High-Frequency Resonant Electro-Optic Phase Modulator
- Three operating wavelengths: 350-700 nm, 400-800 nm, 650-1100 nm
- Resonant frequency: covers 2 GHz-14.75 GHz
- Tunable resonant frequency
Tuniu’s high-frequency resonant electro-optic phase modulators are based on the electro-optic effect and optical resonant cavity principles to achieve optical signal phase modulation. Utilizing the resonance principle, resonant electro-optic phase modulators can effectively reduce the half-wave voltage and increase the modulation depth. The resonant frequency of the high-frequency resonant electro-optic phase modulators is adjustable and can be tuned via the adjustment knob on the device. The signal interface type is SMA. The bottom of the device features M4 threaded holes for easy mounting onto posts. The polarization direction of the incident light must align with the label on the input end.
